Answer:
<h2>The temperature of the gas is 48.75 Kelvin.</h2>
Explanation:
Using the ideal gas equation as shown
PV = nRT where;
P is the pressure of the gas in ATM
V is the volume of the gas
n is the number of moles
R is the ideal gas constant
T is the temperature in Kelvin
From the formula, 
Given the following parameters V = 1litre, n = 0.5moles. pressure = 2ATM
R = 0.08206 atm L/molK
On substituting to get the temperature we have:

Answer:
The mass will stay the same throughout time
Explanation:
It is a 1-minute averaged measure of the hurricane's maximum winds. Westerlies are one of the breeze belts helping to shape and guide hurricanes. A tropical cyclone is a quickly spinning storm system with a low-pressure core, a closed small-level air vortex, gusty winds, and a thunder storm spiral structure that causes torrential rain or squalls.
I think only if they were too overpowered maybe, but the modern world doesn't except this kind of dictatorship. Most armies are much more powerful than in the past.
